: Large Amplitude Pneumatic Oscillator; A system for producing variable amplitude pneumatic pulses, such as may be used to prevent flow separation on airfoil and diffuser surfaces to control stalling, utilizes a source of pressurized air which is regulated and fed to parallel outlet lines. Each outlet line has a control valve therein attached to a controller for activation of the valves. The first parallel line leads to an actuator which supplies the pulsed air to a desired surface. The second parallel line leads to the atmosphere. By cycling the valves at about ninety degrees out of phase, pneumatic pulses of large amplitude are obtained with a simple device capable of being transported on the aircraft., Sponsorship: Illinois Institute of Technology, United States Patent

: Powered Resonance Tubes: Resonance Characteristics and Actuation Signal Directivity; The powered resonance tube (PRT) actuator and its variants are new developments in active flow control (AFC) technology. The PRT is attractive because it has no moving parts and can produce acoustic tones that have amplitudes greater than 150 dB over a large frequency bandwidth. The first part of this paper deals with the resonance characteristics of the PRT as a function of the operating parameters such as jet-to-tube spacing (Sp), tube depth (d), and nozzle pressure ratio (NPR). It was found that: (1) at low NPR (3.33), the PRT resonates at discrete combinations of spacing and depth. (2) Using theoretical estimates for predicting shock cell lengths, one could observe a correlation between the theoretical prediction for shock cell length and the spacing at which the PRT resonates. (3) At high NPR (4.29), for a fixed depth, the PRT resonates at virtually all spacings. (4) The frequency at which the PRT resonates remains approximately constant, regardless of spacing. The second part of the study focused on examining the directivity of the acoustic radiation from the PRT-significant for developing orientation strategies of the PRT with respect to the target flow in the end application. The directivity of the fundamental PRT tone and that of its harmonics were studied for a variety of resonance frequencies, both separately as well as cumulatively. It was found that the fundamental part of the actuation signal radiated predominantly in the downstream direction of the jet for low resonance frequencies. As the resonance frequency was increased from 3 to 12 kHz, the directivity changed from downstream of the jet to vertically upward, and finally upstream of the jet at the higher frequencies., http://dx.doi.org/10.1007/s00348-005-0041-5

: Intelligent real-time performance monitoring and quality prediction for batch/fed-batch cultivations; Supervision of batch bioprocess operations in real-time during the progress of a batch run offers many advantages over end-of-batch quality control. Multivariate statistical techniques such as multiway partial least squares (MPLS) provide an efficient modeling and supervision framework. A new type of MPLS modeling technique that is especially suitable for online real-time process monitoring and the multivariate monitoring charts are presented. This online process monitoring technique is also extended to include predictions of end-of-batch quality measurements during the progress of a batch run. Process monitoring, quality estimation and fault diagnosis activities are automated and supervised by embedding them into a real-time knowledge-based system (RTKBS). Interpretation of multivariate charts is also automated through a generic rule-base for efficient alarm handling. The integrated RTKBS and the implementation of MPLS-based process monitoring and quality control are illustrated using a fed-batch penicillin production benchmark process simulator., Endnote format citation for DOI:10.1016/j.jbiotec.2003.10.004

: Record Medium Transducing Error Correction System and Method; In one exemplary embodiment errors due to tape flutter are overcome by recording along with the analog signal clock pulses having a rate sufficient for sampling of the highest frequency component of the analog signal. Then on playback, the reproduced clock pulses control sampling and storage of samples of the reproduced analog signal. By reading out the samples from storage at a uniform clock rate, the effect of flutter on the reproduced signal is eliminated. In another example the recorded clock rate overcomes tape skew and other mechanical irregularities in recording and reproducing multiplexed analog or digital data., Sponsorship: IIT Research Institute, United States Patent

: Comarch Pocket XL (semester?), IPRO 349F; The objective of this group is to produce barcode scanning software for warehouse acceptance. This means that when a warehouse receives an item (or items) information is generated about that item from its barcode that lets a warehouse worker know where the item should be stored in the warehouse. At the end of this project we should have a solution that is ready for verification of specifications by a Comarch deployers. Our software should meet several criteria:  Integrated into CDN XL which is Comarch ERP solution software.  Make use of its algorithm to improve the efficiency of a warehouse by directing the employees to where items should be stored in the warehouse.  Foolproof to minimize the effects of human error.  Capable of multinational use and will include a language pack for Polish and English.  Have a minimal learning curve in order to be an effective and marketable product. Some aspects of the software should be customizable after the prototype stage such as the format of barcode it will read, what type of mobile device it will run on and the appearance of the graphical user interface. The customization capabilities will not be implemented in this project since our software will be the initial release., Sponsorship: Comarch, Deliverables for IPRO 349F: Comarch Pocket XL for the Summer 2007 semester

: Sustainable Entrepreneurial Economic Development (Summer 2011) IPRO 350; Coal city is a small town in Illinois that has partnered with IIT. Its current population is 5,152 people and has been steadily increasing. Coal City is located just south of I-80 along the I- 55 corridor and less than an hour from Bolingbrook and Oakbrook. Along the northern border of Coal city, are adjoining lakes and abandoned coal mines. Small town atmosphere is conducive to community interaction and pride. The purpose of this project was to provide the framework for creating the most feasible and sustainable economic development model for the village of Coal City using generalized approaches that could be emulated in other small towns. the objectives that the team has set are: Gather information that will lead to the creation of an effective plan. Study models and components of Sustainable Economic Development focusing on small towns and rural areas. Study the demographics, human systems, existing industry systems, bio-physical systems, government and social policy systems and the existing industry clusters. Understand community, local, and regional assets and talent pool, town vision, mission and economic development plans., Sponsorship: NA, Project Plan for IPRO 350: Sustainable Entrepreneurial Economic Development for the Summer 2011 semester
